The Great Schism was not the first or the only divide in Western Christendom, but it was the longest dispute about who was rightfully pope. As two and eventually three groups battled for supremacy representing Rome, Avignon and Pisa, all of Europe was drawn into the debate. The Council of Constance brought together the finest minds, and representatives of all the great authorities of Europe, to solve the problem. Presented by Pat Cullum, Principal Lecturer in Medieval History at the University of Huddersfield.
